Poll: Do you turn the water off when you leave? December 26, 2024 at 3:38 pm #42296 Tim HuckParticipant Joined: Jan 2024 Posts: 20 Likes: 5LikeUp0::We don’t leave water hooked up. We fill our tanks, and when tha is gone, we empty the grey/black and refill with fresh water. BUt if we leave for an extended period of time I still turn the water pump off.
